-4
The solution set consists of the coordinates of all points on the line defined by -3x + y = -1 or, equivalently, y = 3x - 1
x = 0
3x-5=3x+5 There is no solution.
70000000y=35t
-3x = 9x = 9/(-3)x = -3
It's an equation.Here's the solution:3x = x + 62x = 6x = 3
One solution.
(-2,-1)
x = -3, y = 7
x = 3 and y = 2
x=4 or x=-4
Just the one solution.
